To @ZZ whom it may concern: 15 is a perforated ring, which rests upon Be it known that I, HENRY STACEY, of Inthe walls of the cylinder 12 and extends latdianapolis, county of Marion, and State of Inerally on each side to the walls of the outer diana, have invented certain new and useful shell 16, thus forming between the inner and 55 Improvements in Coal-Oil Burners; and I do outer shell an air-chamber17, the outer shell hereby declare that the following is a full, being covered by a perforated plate or cap clear, and exact description thereof, reference 18, the whole burner and its inclosing shell being had to the accompanying drawings, in resting directly upon the grate, as shown in which like numerals refer to like parts. Fig. 1. 60 My invention relates to improvements in The operation of my device is as follows: the construction of heating-burners intended When the valve is opened, oil is admitted to be used with the various grades of hydrothrough the inlet 6 to the oil-chamber 7, and carbon oils and will be understood from the when this has been filled a fire is kindled in following description. the opening'lO just above the grate, and as 65 I5 In the drawings, Figure 1 is a central vertisoon as the chamber 7 is thoroughlyheated cal section through the nre-pot of the stove the oil begins to vaporize and will take tire and burner, showing the relative arrange- Afrom the Haine below, the vapor escaping ment and position of the parts when in use. through the openings in the plate 9, and the Fig. 2 is a top view of the perforated plate flame will fill the space about and be thrown 7o 2O that covers the outershell of the burner. outward by the cone, and rising above will Fig. 3 is a similar view of the perforated ring pass through the ring 15 and upward through which rests upon the inner shell of the burner. the perforations in the top plate 18 and into Fig. 4 is a top view of the name-spreading the chamber above.

What Iclairn as my invention, and desire to Secure by Letters Patent, is the following.:

` 1. An oil-burner comprising a base having an oil-chamber within, a perforated cap, a eentral draft-opening, a hollow perforated de fleeting-cone seated in such opening and extending abovetheburner,aperforated shell inclosing such burner and cone, and an air-chamber formed around Euch perforated shell andbetween it and the wall of an outer inclosing shell having a perforated top, in combination with a supply-pipe tapping,` the oil-charnber and connected l with a suitable tank, and a regulating-valve between the tank and burner, substantially as shown and described. 2. vAn oil-burner comprising a vloase adapted to rest'upon a fire-grate and cored out below,

a triangular oil-chamber in the base Covered by a perforated-cap, a central opening through the burner, a hollow perforated deilectingcone having a neck loosely seated in such central opening, a perforated shell surrounding the cone, an outer shell of greater diameter su rrounding the perforated shell, whereby an air-chamber 4is formed bet-Ween the outer and inner shells, a perforated ring covering the air-chamber, and a perforated cap covering the outer shell, in combination with a su pply-pipe tapping the oil-chamber, its other end connected to the oil-tank, and a regulating-valve between the tank and burner, substantially as shown and described.

, In witness whereof I have hereunto set my hand this 19th dayof November, 1891.
